"The Man From U.N.C.L.E" trailed off in the way of quality after the black and white episodes finished. Those ones are the best by a long way. The colour ones became too silly and quite tiresome. It was always going to be a tongue-in-cheek series but it still maintained a certain level of drama in the first two seasons. Robert Vaughn and David McCallum compliment each other very well in their respective characters. They both have different personalities which helps. The action is fairly mild by today's standards as the violence is of a "comic strip" kind.
